Pawnee Montane Skipper Butterfly Recovery Plan

摘要

The Pawnee montane skipper is a member of the skipper butterfly family (Hesperiidae) and was first described in 1911 as Pamphila montana (Skinner 1911). Scott and Stanford (1982) combined two species (Hesperia pawnee and Hesperia leonardus), retained the specific name leonardus, and treated the Pawnee montane skipper as Hesperia leonardus montana. It was officially listed as Hesperia leonardus montana in the Federal Register as a threatened species on September 25, 1987 (52 FR 36176). The Pawnee montane skipper is a small brownish-yellow butterfly with a wing span slightly over 1 inch. Small, fulvous (dull brownish-yellow), usually distinct spots occur near the outer margins of the upper surface of the wings, while one to four distinct brownish to off-white spots occur on the lower (ventral) surface of the wings. The ventral spots are larger on the hind wing and generally are whiter in the female butterflies.
